Answer: $45
Step-by-step explanation:
Simple interest is calculated as Principal x Rate x Time/100
From the information given,
Principal = $250
Rate = 12% = 12/100 = 0.12
Time = 18 months; because time is given in months, we divide by 12; time is therefore stated as 18/12.
Step 2: Plug the values into the formula:
Simple interest = 250 x 0.12 x 18/12
= $45
D is the answer because 1 and 9
Answer:
A. 42.5
Step-by-step explanation:
The triangle shown is an isosceles triangle. An isosceles triangle haas two of its sides and base angles equal. Hence;
<ACB = <ABC (Base angles are equal)
Given
<ACB = 42.5°
Required
<ABC
<em>According to the law above which says <ACB = <ABC , hence <ABC is also equal to 42.5°</em>

Answer:
x = 6
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
5x = 3x+12
Subtract 3x from each side
5x -3x = 3x+12-3x
2x= 12
Divide by 2
2x/2 = 12/2
x = 6
